You’re standing on the platform at East 180th Street. It’s 8:15 AM. You see a train pulling in, and the digital sign says "5 Express." You jump on, thinking you’re a genius for beating the crowd. Then, ten minutes later, the conductor mumbles something over a static-filled speaker about "switch delays" at 149th Street-Grand Concourse. Suddenly, your "express" ride feels like a slow crawl through a very dark, very loud basement.
The MTA subway 5 train is a bit of a legend in the New York City transit system, but not always for the right reasons. It’s the Lexington Avenue Express that behaves like a local when you least expect it. It’s the only line that feels like it has a split personality, stretching from the dense suburban feel of Eastchester in the Bronx all the way down to the flatlands of Brooklyn. If you’ve ever tried to navigate the "Threeway Split" during rush hour, you know exactly what I’m talking about. It’s chaotic. It’s fast. It’s frequently frustrating.
But here is the thing: if you actually understand how the 5 operates, it’s one of the most efficient tools in your NYC survival kit. Most people just swipe their OMNY and hope for the best. That’s a mistake.
The Bronx Layout That Confuses Everyone
Let’s talk about the geography because this is where the 5 train starts to get weird. Unlike the 4 train, which stays pretty consistent, the 5 has two different northern terminals. You’ve got the Dyre Avenue branch and the Nereid Avenue branch. If you aren't paying attention to the rollsign (or the bright LED lights on the newer R142 cars), you might end up in a completely different neighborhood than you intended.
The Dyre Avenue line is actually a remnant of the old New York, Westchester and Boston Railway. It feels different. The stations are a bit more "stately," even if they’ve seen better days. When you’re riding through Morris Park or Pelham Parkway, you’re on tracks that were originally built for a heavy rail commuter line, not a subway. This is why that stretch of the 5 feels so much smoother and more "open" than the cramped tunnels of Lower Manhattan.
Then there’s the Nereid Avenue service. During rush hours, some 5 trains head up the White Plains Road line, sharing tracks with the 2 train. It’s a logistical nightmare for the MTA dispatchers. Think about it: you’ve got two major lines merging and de-merging at 149th Street and again at East 180th Street. One tiny delay at Gun Hill Road ripples all the way down to Nevins Street in Brooklyn. It’s a house of cards.

Why the Lexington Avenue Express is a Beast
Once the MTA subway 5 train hits 125th Street in Harlem, it enters the busiest subway corridor in the United States: the Lexington Avenue Line. Along with the 4 and the 6, this stretch carries more riders daily than the entire transit systems of some major cities like San Francisco or Chicago.
The 5 is the "flexible" sibling here.
During the day, it skips the local stops, flying past 116th, 110th, 103rd, and so on. It’s a beautiful feeling when you’re on a 5 train that’s actually moving at top speed between 86th Street and 59th Street. You feel like you’re winning at life. But the complexity of the Lexington Avenue line means that the 5 is often the first to be rerouted. If there’s "police investigation" at Grand Central, your 5 train might suddenly decide it’s a local. Or it might decide it’s going to the West Side via the 2 line.
Honestly, you have to stay on your toes. The 5 is the ultimate "audible" play for the MTA.
The Brooklyn Connection and the Flatbush Dilemma
South of Brooklyn Bridge-City Hall, the 5 train continues its journey into Brooklyn, but only on weekdays. On weekends? Forget it. It usually terminates at Bowling Green, leaving the 4 to do the heavy lifting into the outer borough.

But during the week, the 5 heads down to Flatbush Avenue-Brooklyn College. This is another point of confusion. The 2 and the 5 share this terminal. Because it’s a "stub-end" station—meaning the trains pull in and have to pull back out the same way—congestion is a nightmare. You’ll often find your 5 train sitting just outside of President Street or Sterling Street, waiting for a "clearing signal."
It’s an old system. The signals in some of these tunnels date back decades. While the MTA has been slowly installing CBTC (Communications-Based Train Control) on various lines, the 5 train’s route is a patchwork of old and new tech. This is why your 5 train might suddenly lurch to a halt for no apparent reason. The "spacing" between trains is still managed by physical blocks of track in many areas, and the 5 has to play nice with the 2, 3, and 4.
The Gear: What You’re Actually Riding On
Most of the time, you’re riding in R142 or R142A cars. These were the first "New Millennium" trains brought in by the MTA in the early 2000s. They were a massive upgrade from the old "Redbirds" that used to haunt the Bronx. They have clear voice announcements—though we all know the "stand clear of the closing doors" lady's voice a little too well—and decent air conditioning.
However, because these cars are now over 20 years old, they’re starting to show their age. The floors get grimy. The strip maps above the doors sometimes flicker. But compared to the lettered lines (like the A or the F), the 5 train’s rolling stock is actually pretty reliable. The traction motors are robust, and they can handle the steep grades of the Joralemon Street Tunnel under the East River without breaking a sweat.
Survival Tips for the 5 Train Veteran
If you want to master the MTA subway 5 train, you need to stop acting like a tourist. Here is how you actually ride it like a pro.
First, check the "Weekend Subway Service" posters religiously. The 5 train is the king of service changes. Because it shares so much track with other lines, it’s constantly being diverted. One weekend it’s running to South Ferry; the next, it’s not running at all in Brooklyn. Use the MYmta app, but also look at the physical signs. Sometimes the digital signs at the station are slow to update when a train is being "held in the station" due to an emergency.
Second, if you’re at 149th Street-Grand Concourse and trying to get to Manhattan, look at the 4 and the 5. If a 5 is coming first, take it, but try to stay toward the middle of the train. The transfers at Grand Central and Union Square are much easier if you aren't stuck at the very ends of the platform.
Third, understand the "Dyre Ave Shuttle." Late at night, the 5 train doesn't go to Manhattan. It just bounces back and forth between East 180th Street and Dyre Avenue. If you’re trying to get home to the Bronx at 2:00 AM, you’ll need to take the 2 train to East 180th and then transfer. It’s a lonely ride, but it’s consistent.
The Future: Will it Ever Get Better?
There are plans, always plans. The MTA’s "Twenty-Year Needs Assessment" mentions signal upgrades for the Lexington Avenue line, which would theoretically allow for more 5 trains per hour. Right now, the bottleneck is the sheer volume of trains. You can’t just "add more 5s" because there’s no room on the tracks between the 4s and the 6s.
There is also the ongoing work on the 149th Street corridor. It’s one of the most problematic "choke points" in the entire system. If the MTA can ever fully modernize the switching system there, the 5 train might finally lose its reputation for random mid-tunnel pauses.
Until then, the 5 remains the "thinking person's train." It requires you to know the time of day, the day of the week, and the specific branch you’re on. It’s not for the faint of heart, but it’s a quintessential New York experience.
Actionable Takeaways for Your Next Ride
- Check the Branch: Before boarding in the Bronx, look at the front of the train. If it says "Dyre Ave," it’s going toward Eastchester. If it says "Nereid Ave," it’s going toward the North Bronx/Woodlawn area.
- Mind the Clock: Remember that the 5 runs express in Manhattan only during the day and early evening. Late nights and weekends turn it into a different beast (or it doesn't run at all in certain sections).
- The Transfer Trick: If you’re heading to the West Side, transferring to the 2 or 3 at Nevins Street or Atlantic Ave-Barclays Ctr is often faster than going all the way to 42nd Street and walking the long tunnel to Times Square.
- The "Last Train" Rule: Always know when the last 5 train through-service leaves Manhattan if you live on the Dyre Avenue line. Missing that last through-train means an extra 20 minutes waiting for the shuttle at 180th Street.
- Monitor the 4: If the 5 is delayed, the 4 is your best friend. They cover the same ground in Manhattan. If you see a crowd building for the 5, walk to the other side of the platform and wait for the 4. It might be local in Brooklyn, but it'll get you across the river.
